Aliaksandr Kalenik bf5cee9f38 LibWeb: Precompute box shadow geometry at display list recording time ...

Move shadow rect computation, offset translation, and corner radii
spread-distance adjustment from the Skia display list player to the
recording site in ShadowPainting.cpp. This avoids recomputing derived
geometry every time the display list is replayed.

Replace PaintBoxShadowParams with precomputed fields directly on
PaintOuterBoxShadow and PaintInnerBoxShadow command structs. Add
CornerRadii::adjust_corners_for_spread_distance() to centralize the
CSS spec's spread-distance-to-radius adjustment logic.
